In order to meet the different performance requirements of various application scenarios, the study of New Radio (NR) (or 5G) was started at the 72nd plenary meeting of 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network).

[0155] Embodiment 3

[0156] Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3 showing three layers of the radio protocol architecture for the control plane 300 of a terminal and an IoT device: Layer 1, Layer 2, and Layer 3. Layer 1 (LI layer) is the lowest layer and implements various PHY (Physical layer) signal processing functions. The LI layer will be referred to herein as the PHY 301. Layer 2 (L2 layer) 305 is above the PHY 301 and is responsible for the link between the terminal and the IoT device over the PHY 301. The L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, a RLC (Radio Link Control) sublayer 303 (if supported by the IoT device), and a PDCP (Packet Data Convergence Protocol) sublayer 304 (if supported by the IoT device), which are terminated at the IoT device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security through encryption of data packets, and provides mobility management for the terminal device between the IoT devices. The RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of packets to compensate for out-of-order reception due to HARQ (if supported by the IoT device). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating the various radio resources (e.g., resource blocks) in one cell between the first node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring lower layers using RRC signaling between the IoT device and the terminal. The radio protocol architecture of the user plane 350 includes Layer 1 (LI layer) and Layer 2 (L2 layer), which are substantially the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355 (if supported by the IoT device), the RLC sublayer 353 in the L2 layer 355 (if supported by the IoT device), and the MAC sublayer 352 in the L2 layer 355 for the terminal and the IoT device in the user plane 350, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes a SDAP (Service Data Adaptation Protocol) sublayer 356, if supported by the IoT device, which is responsible for mapping between a QoS flow and a data radio bearer (DRB) to support diverse services. Although not shown, the terminal can have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., remote UE, server, etc.).

[0162] Embodiment 4

[0163] Embodiment 4 shows a schematic diagram of a terminal and an IoT device according to one embodiment of the present application, as shown in FIG. 4.

[0164] The terminal (410) can include a controller / processor 440, a memory 430, a reception processor 412, a transmitter / receiver 416 including an antenna 420, and a transmission processor 415.

[0166] In transmission from the terminal to the IoT device, upper layer packets are provided to the controller / processor 440. The controller / processor 440 implements the functionality of the L2 layer and above. The controller / processor 440 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations according to various priority metrics. The controller / processor 440 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the IoT device 450 at higher layers. The higher layer information carried by the first signal (when the first signal carries higher layer information) is generated at the controller / processor 440. The transmit processor 415 implements various signal processing functions for the LI layer (i.e., physical layer) such as coding, interleaving, scrambling, modulation, power control / assignment, precoding, and physical layer control signaling generation, etc. such as the physical layer signal carrying the first signal is completed at the transmit processor 415. The generated modulation symbols are then split into parallel streams, one for each transmit antenna 420, and the streams are mapped to the subcarriers and / or symbols, respectively, at the frequency domain multiplexor 425 under direction of control processor 440. The streams are then combined together according to a particular beamforming matrix that is selected based on the wireless channel of the terminal 410, and the combined streams are then transmitted via the antennas 420 through the transmitter 416 in the form of radio frequency signals. At the terminal 410, each receiver 456 receives a signal through its respective antenna 460, and each receiver 456 recovers the baseband information (if baseband processing is supported) modulated on the radio frequency carrier wave and provides the baseband information to the receive processor 452. The receive processor 452 implements various signal processing functions of the LI layer. The signal processing functions include receiving the physical layer signal carrying the first signal in the present application, performing various demodulation schemes based on the various modulation schemes (e.g., on-off keying (OOK), binary phase shift keying (BPSK), etc.), descrambling, decoding, and deinterleaving (if supported) to recover the data or control transmitted by the IoT device 450 on the physical channel, and then providing the data and control signals to the controller / processor 490 (if the terminal supports). The controller / processor 490 is responsible for the L2 layer and above, and the controller / processor 490 interprets higher layer information. This includes interpreting the higher layer information carried by the first signal. The controller / processor can be associated with a memory that stores program codes and data. The memory can be referred to as a computer readable medium.

[0167] In transmissions from the IoT device to the terminal, and similarly from the terminal to the IoT device, higher layer information, after being generated at the controller / processor 490 if the IoT device supports it, is subjected to various signal transmission processing functions for the LI layer (i.e., physical layer) by the transmit processor 455, which maps to the antennas 460 via the transmitters 456 for transmission as radio frequency signals. The receivers 416 receive the radio frequency signals through their respective antennas 420, each of which recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receive processor 412. The receive processor 412 implements various signal reception processing functions for the LI layer (i.e., physical layer) and then provides the data and / or control signals to the controller / processor 440. The functions of the controller / processor 440 include the interpretation of higher layer information. The controller / processor can be associated with a memory that stores program codes and data. The memory can be a computer readable medium.
